Astragalus Membranaceus Shows Potential Skin and Anti-Aging Benefits: Review
USA: A review published in the Journal of Drugs in Dermatology highlights that Astragalus membranaceus, a natural plant-based ingredient commonly used in skincare products, may provide multiple skin benefits. The ingredient appears to support collagen production, antioxidant activity, and skin barrier function, contributing to overall skin health and potential anti-aging effects. Researchers suggest that Astragalus membranaceus may serve as a supportive adjunct to established, evidence-based skincare practices, rather than a standalone treatment.
Skin aging is driven by a combination of intrinsic processes and environmental exposures. Oxidative stress, ultraviolet (UV) radiation, and gradual cellular decline contribute to visible signs such as wrinkles, uneven pigmentation, and reduced elasticity. As interest in plant-derived compounds grows, botanicals with antioxidant and anti-inflammatory properties are increasingly being explored for their role in dermatologic care. In this context, Stephanie Jackson, BA, of A.T. Still University School of Osteopathic Medicine, Mesa, Arizona, and colleagues conducted a systematic review to evaluate the anti-aging and pigment-modulating potential of Astragalus membranaceus.
The authors performed a structured PubMed search covering studies published between 2015 and 2025, following PRISMA guidelines. Both laboratory-based and clinical investigations examining the dermatologic effects of Astragalus membranaceus were included. The review focused on its key bioactive constituents—such as astragaloside IV, cycloastragenol, flavonoids, and polysaccharides—and their roles in skin protection and rejuvenation.
The researchers reported the following findings:
- The bioactive compounds demonstrated multiple protective effects at the cellular level.
- They were shown to reduce reactive oxygen species (ROS), helping to limit oxidative stress–related skin damage.
- Suppression of pro-inflammatory signaling pathways was observed, indicating potential anti-inflammatory benefits.
- Preservation of mitochondrial function was reported, supporting cellular energy balance and resilience.
- Several studies found increased collagen synthesis, which is essential for maintaining dermal firmness and reducing wrinkle formation.
- Astragaloside IV was linked to telomere elongation under oxidative stress conditions, suggesting a possible role in promoting cellular longevity.
- Clinical studies, although limited, reported improvements in skin hydration among users of formulations containing Astragalus membranaceus extract.
- Participants also experienced more even skin tone and a visible reduction in fine lines.
- The clinical outcomes were consistent with laboratory findings, indicating enhanced skin barrier integrity and strengthened antioxidant defenses.
Despite these encouraging results, the authors caution that current evidence remains preliminary. Many studies are small in scale or short in duration, and long-term safety data are limited. The review underscores the need for well-designed randomized controlled trials to clarify optimal formulations, dosing strategies, and sustained clinical benefits.
Overall, the evidence summarized in this review positions Astragalus membranaceus as a promising botanical ingredient in cosmeceutical formulations targeting pigmentation and skin aging. While not a replacement for established dermatologic therapies, it may offer complementary benefits when incorporated into comprehensive, evidence-based skincare regimens.
